A friend gave me mpeg2 file which mplayer plays back with wrong aspect
ratio. It was ripped from 480x480 NTSC SVCD, the correct aspect ratio
should be 4/3, however mplayer sets 1:1 aspect and prints this message
upon playback:

Detected unknown aspect_ratio_information in mpeg sequence header.
Please report the aspect value (14) along with the movie type
(VGA,PAL,NTSC,SECAM) and the movie resolution
(720x576,352x240,480x480,...) to the MPlayer developers, so that we can
add support for it!
Assuming 1:1 aspect for now.
VIDEO:  MPEG2  480x480  (aspect 14)  23.976 fps  2518.0 kbps (314.8
[V] filefmt:2  fourcc:0x10000002  size:480x480  fps:23.98  ftime:=0.0417

Right now I remuxed the file with -mpegopts vaspect=4/3, however I
wonder if original file had wrong aspect ratio or 14 is some meaningful
yet unrecognised by mplayer value.
